Iron meteorite Chinga was classified as ataxite IVB with about 16.8 wt.% of Ni. The main part of metal was presented by plessite (a-Fe(Ni, Co) + g-Fe(Ni, Co) mixture) that was not optically resolvable. It is also well known the presence of macroscopic selective reflection bands (Schliren bands or oriented sheen) in various nickel-rich ataxites IVB [1, 2]. However, the origin of Schliren bands is not clear yet. There were several different suggestions such as variety of chemical and phase compositions, shock alteration, and twinning to explain Schliren bands formation, but these explanations were not evident. Therefore, various nanoscopic techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM) with electron backscattering diffraction (EBSD), atom probe microscopy (APM) and Mössbauer spectroscopy with high velocity resolution were used for complex multi-scale study of Chinga metal.
